본 고안은 습한 공기를 건조시켜서 사용처에 공급하는 공기 건조장치에 관한 것으로, 특히 3방향의 통로를 가지는 유입 및 유출밸브를 장착한 공기 건조장치에 관한 것이다.The present invention relates to an air dryer for drying and supplying wet air to a user, and more particularly, to an air dryer equipped with an inlet and an outlet valve having a three-way passage.

종래에는 도면 제5도에서와 같이 유입밸브(20)만을 장착하되 이 유입밸브(20)는 4방향의 통로를 가지고 있는 것으로, 별도의 인위적인 조작에 의해서 동작되며 각 제습탱크(C)(D)로부터 유출되는 건조공기를 배출하는 각각 배출밸브(21)(22)와 배출되는 건조공기의 재활용을 유동하는 복귀밸브(23)(24)등을 구비하여 사용하였던 것으로, 이와 같은 다수의 밸브와 밸브를 동작시키는 전기적 장치의 필요로 인하여 제작 및 설치비가 많이 드는 결함이 있으며, 공기회로가 복잡하고 조작이 까다로울뿐 아니라 유입밸브(20)의 구조가 복잡하며, 장시간 사용하면 마모가 되어 기밀유지가 곤란한 문제가 있었던 것이다.Conventionally, as shown in FIG. 5, only the inlet valve 20 is mounted, but the inlet valve 20 has a passage in four directions, and is operated by a separate artificial operation and each dehumidification tank (C) (D). A plurality of valves and valves were used to provide discharge valves 21 and 22 for discharging dry air discharged from the discharge valves and return valves 23 and 24 for recycling recycled dry air discharged therefrom. Due to the need for an electrical device to operate the manufacturing and installation costs a lot of defects, the air circuit is complicated and difficult to operate as well as the structure of the inlet valve 20 is complicated, and long-term use is difficult to maintain airtight There was a problem.

이러한 종래의 문제점을 없애고 제작 및 설치가 간단하고 사용이 간편한 공기 건조장치를 제공하고자 안출한 본 고안은, 유입 및 유출구에 3방향의 통로를 가지는 셔틀 밸브를 장착하여 양측 통로의 압력차에 의한 자동적인 동작이 가능하도록 하므로서, 부대설비를 줄이고 제작비를 줄이는 한편 기밀 누설에 전혀 없도록한 것이다.The present invention devised to eliminate the conventional problems and to provide an air drying apparatus that is simple to manufacture and install and easy to use, is equipped with a shuttle valve having a three-way passage at the inlet and outlet, and automatically In order to enable the operation, it is possible to reduce the auxiliary equipment, reduce the manufacturing cost and to prevent leakage at all.

이와 같은 본 고안의 구성을 첨부 도면에 의하여 설명하면 다음과 같다.Referring to the configuration of the present invention as described in the accompanying drawings as follows.

첨부 도면 제1도는 본 원장치의 밸브 조작에 따른 공기흐름을 나타낸 공정도이고, 제2도는 본 고안상의 셔틀밸브의 단면을 도시한 것이다. 이에 나타낸 바와 같이, 내부에 왕복피스톤(1)을 가지고 3방향의 통로(2)(3)(4)를 가지는 유입측 셔틀 밸브(5)의 양측 통로(2)(3)에 A측 및 B측 유통로(6)(7)를 각각 연결하여 각각 A측 제습탱크(A) 및 B측 제습탱크(B)에 연결하고, 상기 각 유통로(6)(7)의 일단에 재생공기 배출밸브(8)(9) 및 소음기(10)(11)를 각각 연결하며, 상기 A측 제습탱크 및 B측 제습탱크로 부터 인출되는 유통로(12)(13)의 타단을 유출측 셔틀 밸브(5')의 양측으로 각각 연결하고, 오리피스(14) 및 압력제거(15)를 가지는 오리피스관(16)을 유출측 셔틀밸브(5')의 양측 유통로(12)(13)에 연결 설치하며, 건조공기 보충밸브(17)를 가지는 유통로(18)를 유출측 셔틀밸브(5')의 배출측 통로에서 인출 하여 그 타단을 상기 오리피스관(16)의 일단에 연결하여 구성한다.1 is a process chart showing the air flow according to the valve operation of the original device, Figure 2 is a cross-sectional view of the shuttle valve according to the present invention. As shown here, A side and B in both side passages 2 and 3 of the inlet-side shuttle valve 5 having the reciprocating piston 1 therein and having the passages 2, 3 and 4 in three directions. Each side flow path (6) (7) is connected to each of the A side dehumidification tank (A) and B side dehumidification tank (B), respectively, and the regeneration air discharge valve at one end of each of the flow paths (6) and (7). (8) (9) and the silencer (10) and (11), respectively, and the other end of the flow passages (12) (13) drawn out from the A side dehumidification tank and the B side dehumidification tank (5) Respectively connected to both sides of the '), and the orifice tube 16 having the orifice 14 and the pressure relief 15 is connected to both side flow paths 12 and 13 of the outlet shuttle valve 5', The flow passage 18 having the dry air replenishment valve 17 is drawn out of the outlet side passage of the outlet shuttle valve 5 'and the other end thereof is connected to one end of the orifice tube 16.

여기서, 미설명 부호 19은 압력계이다.Here, reference numeral 19 is a pressure gauge.

이와 같은 본 고안의 작용 및 효과를 상세히 설명하면 다음과 같다. 첨부 도면 제3도 및 제4도는 유입측 셔틀밸브의 동작상태를 나타낸 것으로, 제3도는 A측 제습탱크로 유입될때이며, 제4도는 B측 제습탱크로 유입될 때를 나타낸다.Referring to the operation and effects of the present invention in detail as follows. 3 and 4 show an operating state of the inlet shuttle valve, and FIG. 3 shows when it enters the A side dehumidification tank, and FIG. 4 shows when it enters the B side dehumidification tank.

제1도에 의하여 본 원장치의 작용을 설명하면, A측 제습탱크에 습한 압축공기가 유입될때에는 이 압축공기가 화살표(←)와 같이 유입측 셔틀밸브(5)를 통과하여 건조제가 채워진 A측 제습탱크로 유입되는데, 이때, 셔틀밸브(5)의 왕복피스톤(1)은 도면 제3도에서와 같이 B측 통로(3)를 막아주게 되며, A측 유통로(6)의 공기 배출밸브(8)는 닫혀 있게되고, B측 유통로(7)의 공기 배출밸브(9)는 열려 있게된다. A측 제습탱크로 유입된 압축공기는 수분이 제거된 상태가 되어 유출측 셔틀밸브(5')를 통하여 사용처에 공급되며, 이때, 유출측 셔틀밸브(5')의 왕복피스톤(1')은 공기압에 의해 밀려서 B측 통로를 막게된다. 이와 같이, A측 제습탱크가 제습동작을 계속하는 동안 B측 제습탱크는 탱크내의 수분을 제거하는 재생동작을 하게 되는데, 즉, 상기 A측 제습탱크에서 유출되는 건조공기의 일부가 오리피스관(16)을 통하여 B측 제습탱크로 보내져서 B측 제습탱크의 수분을 제거하게 되는 것이다.Referring to the operation of the main device according to FIG. 1, when wet compressed air flows into the A side dehumidification tank, this compressed air passes through the inlet shuttle valve 5 as shown by the arrow (←) and is filled with a desiccant. It flows into the side dehumidification tank. At this time, the reciprocating piston 1 of the shuttle valve 5 blocks the B side passage 3 as shown in FIG. 3, and the air discharge valve of the A side flow passage 6 (8) becomes closed, and the air discharge valve 9 of the B side flow path 7 remains open. The compressed air introduced into the A side dehumidification tank is in a state where water is removed and is supplied to the place of use through the outlet shuttle valve 5 '. At this time, the reciprocating piston 1' of the outlet shuttle valve 5 'is It is pushed by air pressure to block the B side passage. As such, while the A side dehumidification tank continues the dehumidification operation, the B side dehumidification tank performs a regeneration operation to remove moisture in the tank, that is, a part of the dry air flowing out of the A side dehumidification tank is orifice tube 16. Is sent to B side dehumidification tank to remove moisture from B side dehumidification tank.

이때, 건조공기는 오리피스관(14)를 통과하면서 충분히 팽창되어 초건조상태로 되며, 재생에 필요한 건조공기의 양이 부족할 경우 건조공기 보충밸브(17)를 적절히 공기를 보충하면 된다. 이와 같이, B측 제습탱크의 건조제를 재생하여 다량의 수분을 갖게 되는 재생공기는 B측 유통로(7)를 거쳐 B측 재생공기 배출밸브(9) 및 소음기(11)를 거쳐서 대기중으로 배출되며 B측 제습탱크는 수분을 흡수할 수 있는 능력을 갖추게 된다.At this time, the dry air is sufficiently expanded while passing through the orifice pipe 14, and the dry air is in a dry state. When the amount of dry air required for regeneration is insufficient, the dry air supplement valve 17 may be replenished with air appropriately. As such, the regenerated air that has a large amount of moisture by regenerating the desiccant of the B side dehumidification tank is discharged into the atmosphere through the B side flow passage 7 and through the B side regeneration air discharge valve 9 and the silencer 11. The B side dehumidification tank has the ability to absorb moisture.

이러한 건조와 재생동작이 계속되다가 일정시간이 지나면 자동제어반의 타이머(도면에 도시 안됨)가 동작되어 B측의 재생공기 배출밸브(9)가 닫혀지게 되고 B측 제습탱크에는 재생용 공기가 계속 인입되어 B측 제습탱크와 A측 제습탱크와의 압력이 같아지게 된다. 이때, 자동제어반에서 A측의 재생공기 배출밸브(8)를 열어주면 A측 제습탱크에 충만되어 있던 압축공기가 일시에 재생공기 배출밸브(8)를 통하여 대기로 방출되며, 따라서 B측 제습탱크의 압력보다 A측 제습탱크의 압력이 낮아져서 유입측 셔틀밸브(5)의 왕복피스톤(1)이 도면 제4도에서와 같이 통로 쪽으로 이동하여 A측 통로를 막게된다. 동시에 압축공기는 화살표(←)와 같이, B측으로 유입되어 건조도어서 유출측 셔틀밸브(5')의 피스톤을 밀면서 사용처로 계속적인 공급을 하게 되며, A측 제습탱크는 재생동작을 하게 되는 것이다.After the drying and regeneration operation continues, a timer (not shown) of the automatic control panel is operated to close the regeneration air discharge valve 9 on the B side, and regeneration air is continuously introduced to the B side dehumidification tank. Therefore, the pressure between the B side dehumidification tank and the A side dehumidification tank becomes equal. At this time, when the regeneration air discharge valve 8 on the A side is opened by the automatic control panel, the compressed air filled in the A side dehumidification tank is temporarily discharged to the atmosphere through the regeneration air discharge valve 8, and thus the B side dehumidification tank. The pressure of the A side dehumidification tank is lower than the pressure of the reciprocating piston (1) of the inlet shuttle valve 5 is moved toward the passage as shown in Figure 4 to block the A side passage. At the same time, compressed air flows into the B side as shown by the arrow (←) and continues to be supplied to the place of use while pushing the piston of the outlet shuttle valve 5 'to the dry side, and the A side dehumidification tank performs the regeneration operation. .

상술한 바와 같은 본 고안은 제작 및 설치비를 줄일 수 있고 복잡한 부대설비를 줄이는 한편, 작동이 확실하여 기밀이 유지되고 조작이 간편한 효과가 있다.The present invention as described above can reduce the manufacturing and installation costs, and reduce the complicated auxiliary equipment, while the operation is secured, the airtightness and the operation is easy to operate.
